Default Husqvarna 81

Well I finally got around to making a muffler for the big Huskey (thanks to "Mr. Muffler" Ken Lambert) Just got through running it, 6870 on a Zinger 24x10 and 6030 on a PK Plus 24x10. According to the Thrus/HP program, that's 7.6hp and 44.31lbs of thrust on the Zinger! Even though the numbers are a good bit lower with the PK Plus, it was pulling harder, I had to put my full weight on the test stand to keep it from moving :stupid:

It wasn't any harder to convert than any of the other chainsaw engines that have the crankcase built into the saws cases You can do most of the cutting with a bandsaw or scrollsaw. I made a cut across the back of the crankcase with a flycutter for the engine mount plate and made a small flat on the side of the case where I mounted the ignition sensor bracket.
There are a bunch of good brands of saws out there, so that choice is up to you. Try your local saw shops to see if they have any in their pile in the back. I've seen some good motors come from pawnshops (got a couple myself) and I've been burned buying a $25 Poulan 54 from the pawnshop. Ended up having to buy a new piston, cylinder, and rings for that one, but even it turned out ok. $104 for the motor parts, $8 for new bearings and I had a like new 54cc motor that will be going into my Texas Hurricane sometime next week.

Ronbo, I have a 88cc husky that looks just like flipflop's engine but had a compression release on the front. All it needs to be finished up and running is a sensor mounted to the case. I would make you a good deal on it if you are interested. It has a new Zinger 26x10 prop installed. It has a new piston, ring, and rod bearing. Email me at [email protected] if you are interested. I can send you pics of it.

Hello Flipflop: I have the parts of the Husqvarna 281, but I don,t figure how you fix the
motor to the firewall, can you help with your technique?

I`m an Husqvarna dealer, get the new parts is easy, and some cheap, compared to any other
engine in that class, and I know it have a very good horsepower output, and reliability, will
assemble it and see how it works

What about the weight?

I milled the back of the crankcase flat with a flycutter and made the mount out of some .200 thick aluminum plate. The crankcase bolts hold the mount in place. Man, it's been a while since I weighed it, search for "flipflop" in this forum and see if I mentioned the weight in the original post.
